Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_version_level: i16

The new maximum version level for the finalized feature. A value >= 1 is valid. A value < 1, is special, and can be used to request the deletion of the finalized feature.

Supported API versions: 0-1

allow_downgrade: bool

DEPRECATED in version 1 (see DowngradeType). When set to true, the finalized feature version level is allowed to be downgraded/deleted. The downgrade request will fail if the new maximum version level is a value that’s not lower than the existing maximum finalized version level.

Supported API versions: 0

upgrade_type: i8

Determine which type of upgrade will be performed: 1 will perform an upgrade only (default), 2 is safe downgrades only (lossless), 3 is unsafe downgrades (lossy).

Supported API versions: 1

unknown_tagged_fields: BTreeMap<i32, Vec<u8>>

Trait Implementations

impl Builder for FeatureUpdateKey

type Builder = FeatureUpdateKeyBuilder

The [derive_builder::Builder] type for this protocol item.

fn builder() -> Self::Builder

Retrieve the builder for this protocol item.

impl Clone for FeatureUpdateKey

fn clone(&self) -> FeatureUpdateKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FeatureUpdateKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FeatureUpdateKey

fn default() -> Self

Returns the “default value” for a type.

impl Message for FeatureUpdateKey

const VERSIONS: VersionRange = _

The valid versions for this message.

impl PartialEq<FeatureUpdateKey> for FeatureUpdateKey

fn eq(&self, other: &FeatureUpdateKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
